WebEinstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a photon), you get hv=pc. WebLight particles are called photons. The energy carried by each photon can be calculated by the formula of energy of the photon, which is given as E (Photon energy) = h (Plank’s …
